I don't believe that has been determined yet, at least not publicly. My understanding is that it will be a class C misdemeanor w/ an escalating fine for each subsequent offense.
If I were you I would not let this essentially unenforceable law change your plans one bit. In fact should you get a ticket for breaking this ludicrous law while taking a recently disabled vet road cruising, I will pay the fine for you. After all, that is the least I could do for someone who has served our country while enduring such personal sacrifice. It sure is a shame that this ridiculous law is a concern to anyone, let alone someone who has given so much.
I now live in Alpine and on you next trip should you want to come by my house to see some alterna let me know and I will be glad to have you guys over.
I hope you have a great time on your trip and you see lots of herps on what may be the best/most fun road to cruise for herps, in the country. The scenery is of course, wonderful as well, so make sure you get there before dark.
